JOI-IN' TI-IAUBALD, OF ELKINS, WEST VIRGINIA.

' REEEIGERATOR.

Specification of Letters Patent.

Patented July 5, 1910.

Application filed April 29, 1910. Serial No. 558,463.

To all whom it may concern:

Be it known that I, JOI-IN THAUBALD, a citizen of the United States,residing at Elkins, in the county of Randolph and State of WestVirginia, have invented new and useful Improvements in Refrigerators, ofwhich the following is a specification.

My invention relates to improvements in refrigerators, and has for itsobject the provision of means for utilizing atmospheric air as therefrigerating medium.

To the accomplishment of the recited object, and others coordinatetherewith the preferred embodiment of the invention resides in thatconstruction and arrangement of parts hereinafter described, illustratedin the accompanying drawings, and embraced within the scope of theappended claim.

In said drawings: Figure l is a plan view in section of the cooler andcounter'. Fig. 2 is a vertical sectional elevation of the apparatus.Fig. 3 is a side elevation of the counter. Figs. 4 and 5 are transversesectional views taken along lines 4-4 and 5--5 of Fig. 2, and Fig. 6 isa detail perspective view of the air ingress conduit and blowercontainer.

Similar reference characters designate corresponding parts throughoutthe several views. y

Referring more particularly to the drawings for a detail description ofmy invention, the numerals 1 and 2 designate respectively the cooler ormain refrigerator and the counter-refrigerator. The cooler comprises areceptacle with double or triple side walls, top, ends and bottomdesigned to render the contents thereof less susceptible to the inluenceof exterior temperature. Suitable doors, as well as a ventilator' 3, arealso provided. The counter-refrigerator is substantially rectangular inshape with air chambers 4 and 5 extending from the bottom to the top atopposite ends thereof. Transverse partitions 6 constitute the innerwalls of said chambers, and in addition, serve to sustain thelongitudinally disposed shelf 7 and support the pipes 8, which projecttherethrough into the said chambers, as clearly shown in Fig. 1.Communicating with the .sponding wall of the chamber 5, and the fiatbase 11 has an opening 13 to permit the passage of the air from saidchamber into the conduit, and thence through the open end of the latterinto the cooler. As exhibited in Fig. 1 the counter-refrigerator isVequipped with a plurality of doors 14, one

for each air chamber and two for the central chamber.

In practical use the air is drawn in the chamber 4 through the intakepipe 9, through the pipes 8, then into the chamber 5, opening 13, andthrough the pipe 10 to the interior of the cooler by the action of theblower. This operation results in dispelling the warm and vitiated airfrom both the counter and the cooler. In the winter I propose to makeuse of the cooling qualities of the outside atmosphere, and in thesummer resort can be had to placing ice upon the pipes 8, as indicatedby dotted lines in Fig. 2, in which case the air in its travel willbecome cooled by the proximity of the ice, and the cooling influencethereof radiated to both air chambers and the upper portion of thecounter.

It should be understood that in its broader aspects the inventioncomprehends the employment not only of the various means described, butof equivalent means for performing the recited functions. While thearrangement shown is thought at the present time to be preferable, it isdesired to reserve the right to effect such modifications and variationsthereof as may come fairly within the scope of the appended claim.

What is claimed, is.:

In an apparatus of the character described, the combination with acooler of a counterrefrigerator, the latter having terminal airchambers, pipes connecting said chambers, a

central ice chamber, a pipe having one end 100 closed by the Wall of oneof said chambers In testimony Whereof I have hereunto set and the otherend open and extending into my hand in presence of two subscribingWltsaid cooler, said pipefurthermore having a nesses.
